Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007890, here are decompositions:

  • 3 + 1007887 = 1007890
  • 17 + 1007873 = 1007890
  • 29 + 1007861 = 1007890
  • 71 + 1007819 = 1007890
  • 83 + 1007807 = 1007890
  • 89 + 1007801 = 1007890
  • 101 + 1007789 = 1007890
  • 131 + 1007759 = 1007890

Showing the first eight; more decompositions exist.
